How to Make Perfect Beef and Broccoli by Chef Jet Tila | Lee Kum Kee Recipes · Lee Kum Kee USA
Chef Jet Tila demonstrates velveting sliced flank steak with cornstarch, hard searing in a skillet, and tossing with crisp broccoli.
- Target //Cook at High Heat for 18 mins (flip at 3 mins).
- Doneness //Pull when internal temperature reaches 145°F (USDA safe minimum).
- Golden Rule //The secret to restaurant-quality stir fry at home is a screaming hot pan and not touching the beef for the first three minutes. That sear is everything.
- Family Tweak //Reduce the ginger and skip the green onions if kids are picky. Serve over plain white rice and let them dip the beef in extra soy sauce.

Step by step
Tap a step to cross it offPrep the Steak and Sauce
Slice 1.5 lbs flank steak against the grain into 1/4-inch strips. Toss with 1 tbsp cornstarch, 1 tbsp soy sauce, and 1 tsp sesame oil. In a small bowl, whisk together 3 tbsp soy sauce, 1 tbsp rice vinegar, 1 tbsp brown sugar, 1 tsp cornstarch, and 1 tsp sesame oil for the sauce.
WhySlicing against the grain and coating with cornstarch creates velvety tender beef with a light crust that holds sauce perfectly.
Sear the Beef
Heat 1 tbsp vegetable oil in a 12-inch skillet over high heat until just smoking. Add the beef strips in a single layer and sear for 3 minutes without stirring. Flip and cook 1 minute more until browned. Transfer beef to a plate.
WhyDo not overcrowd the pan. If your skillet is smaller, sear the beef in two batches so it browns instead of steaming.
Cook the Broccoli
Add another splash of oil to the same skillet. Add 4 cups broccoli florets, 2 minced garlic cloves, and 1 tsp grated ginger. Stir fry for 1 minute, then add 2 tbsp water and cover for 2 minutes until broccoli is bright green and crisp-tender.
WhyAdding a small splash of water and covering creates steam that cooks the broccoli through without making it mushy.
Combine and Glaze
Return the seared beef to the skillet. Pour the sauce mixture over everything and toss for 30 seconds until the sauce thickens and coats the beef and broccoli. Remove from heat. Garnish with sesame seeds and sliced green onions.
WhyThe sauce thickens fast once it hits the hot pan. Have everything ready before you pour it in so you can toss immediately.
